loadImage and URLs

Not sure if this is a bug or feature, but loadImage can't read anything from URLs, (I am in application mode).
( This is as a result of testing my suggestion here: http://proce55ing.net/discourse/yabb/board_Proce55ing_Software__action_display_num_1039710310.html )
Error is:
Code:
Uncaught error fetching image:
java.lang.NullPointerException
at sun.awt.image.URLImageSource.getConnection(Unknown Source)
at sun.awt.image.URLImageSource.getDecoder(Unknown Source)
at sun.awt.image.InputStreamImageSource.doFetch(Unknown Source)
at sun.awt.image.ImageFetcher.fetchloop(Unknown Source)
at sun.awt.image.ImageFetcher.run(Unknown Source)

example code used:
Code:
void setup() {
size(700,61);
}
void loop() {
BImage d = loadImage("http://riot.com.au/i/title-bar.gif");
for(int i = 0; i < 700*61; i++) {
pixels[i] = d.pixels[i];
}
}

nah, that'd be a bug, or at least an oversight..
because of java security issues (can only connect back to the site from which the applet came) i only ever focussed on getting images from within that same directory as the applet.. though url support would be useful too.
it should be easy enough to add, i'll try and write the extra few lines to check for http:// and proceed accordingly.
